Lumiera error handling (C++ interface).

This header declares the Lumiera exception hierarchy, plus some of the most commonly used error flag values. Within Lumiera, C-style error states and C++-style exceptions are tightly integrated. Creating an exception sets the error flag, and there are helpers available to throw an exception automatically when a unclear error state is detected.

convenience shortcut for a sequence of catch blocks just logging and consuming an error.

Typically this sequence will be used within destructors, which, by convention, must not throw
